The present invention refers to mechanical movements in general, andmore particularly to an articulated mechanism for the transmission ofmovements, which transforms substantially a 5 perceptibly oscillatingmovement into a displacement along perfect horizontal planes.

The composite mechanical movement according to the present mechanism, isessentially obtained by means of a lever having a variable form andsection, which will revolve with or on an adequate axis, and form thefirst section of same; the second section is constituted by a leverarticulated with the former one which will also be supported freely onan axis or fulcrum arranged on the first lever, and a slide that can beslipped along with facility on the first lever, as will be made apparentwith all clarity in the following description. With a determinedeccentricity in connection with the axis of the said first lever,another axis or fulcrum is arranged with which, or over which willrevolve the end of a connecting rod, and with its opposite end revolvingon an axis provided on the slide or runner piece to which mention hasbeen made before; in such a manner that the said runner piece, due tothe trajectory which the said connecting rod obliges it to follow, maydetermine the displacement of the second section of the lever along thehorizontal planes. 30 In view of the foregoing, the principal object ofthe invention consists in providing a perfected mechanism for obtainingthe transformation of a radial movement into a movement or displacementalong horizontal planes, for its application to an infinite number ofindustrial uses and purposes.

The characteristic details of the present mechanism shall be madeapparent with all clarity in the following description, as well as inthe drawing accompanying it as an illustration, in which drawing thereference signs indicate the different parts that compose the saidmechanism.

In the drawing:

The only figure shown presents a partial eleva- 5 tion of the presentmechanism or mechanical movement, in accordance with the invention,wherein there can be clearly seen the different parts which compose it,and another position of its movement by means of broken lines.

I believe it convenient to mention that the drawing illustrates as anexample only, a form for carrying out the purposes of the invention, butthat this is not in any way limited to the secondary specific details asare illustrated and described; variations and modifications can beeffected without departing from the principles and scope of theinvention, and naturally within the purview of the clauses of thechapter of claims.

With specific reference to the attached drawing, the mechanism comprisesa central supporting piece or post III, in which the lever II rests, ofa variable form and section, Whose lever or section II will revolve withor on an adequate axis I2 arranged on the mentioned post I; thementioned lever II constitutes the first section of the mechanism. Thesecond section is constituted by the lever of special form I3, whichrevolves or is supported freely on an axis or fulcrum I4 arranged on theend of the first section or lever II.

Referring again to the lever II, the latter has a slide I5 provided, oflike variable form and section, which can slip with facility along overthe length of sameand whose trajectory over the said lever is determinedby the stop plates or guides I6. At the end of the mentioned slide I5,the axis I1 is located, which supports the second section of the leverI3, with respect to its rotation on the axis I4, as arranged on thelever II. With a determined eccentricity with respect to the axis orfulcrum I2, of the first section of the lever, another axis or fulcrumI8 is located, with which or over which there revolves the anterior endof a connecting rod I9, whose opposite end revolves on the axis 20,mounted at a precalculated distance precisely on the slide or runnerpiece I5, or the first section or lever II. The said slide or runnerpiece I5, due to the trajectory which the said connecting rod I9 obligesit to follow, upon the movement of the lever I I, on its axis I2, maydetermine the displacement of second section or lever I3, alongperfectly horizontal planes, due to the action of the axis or fulcrum Hwith respect to I4.

For the purpose of diminishing the presure at the point of contact ll,of the slide I5 with the second section of lever I3, both sections maybe united with a spring or elastic piece 2 I, by means of the small ironplate 22 fastened to the lever I I, and 23 fastened to I3; in thismanner the sprmg or elastic piece 2|, will tend to maintain the samedirection-towards the two sections before mentioned, diminishing thepresure, and consequently, the losses on account of friction, at theplace of contact H.

The mechanism may be composed of one or several devices as the onedescribed.

Having thus described the invention, what I consider as new and desireto secure by Letters Patent is:

1. An articulated mechanism for the transformation of oscillatingmovements into movements displaceable along horizontal planes,comprising a first lever section mounted for oscilla- 7 tion, a secondlever section articulated With the first lever section, a slide movablelongitudinally of the first lever section, an element carried by theslide having movable connection with the second lever section, and aconnecting rod mounted with a predetermined eccentricity to the axis ofthe first lever section and connected With a predetermined eccentricityto the slide, whereby the slide movable under the operation FRANCISCQROIG IBAfiEZ.
